39results about How to "Avoid Data Transfer Errors" patented technology

An ARQ system and method for a BWA communication system are provided. A transmitter activates an ARQ timer if exist transmission data or retransmission data and transmits the transmission data or the retransmission data to a receiver. The transmitter then receives a response signal for the transmitted data or the retransmitted data and stops the ARQ timer in the not exist of transmission data.

The method and circuit provide an effective implementation to handle the data transferring problem between multiple clock domains. A shift circuit shifts the incoming data stream and a sampling module sequentially samples and outputs each signal in the first group signals and the second group signals by the N sampling pulses with a sequence.

The embodiment of the invention, which relates to the wireless communication technology field, discloses an information notification and timing advance (TA) obtaining method, a system and equipment thereof. The method, the system and the equipment are used to solve a problem that how a terminal acquires the TA used in uplink transmission on a new added cell when a polymerization cell is added for the terminal. In the invention, the method is characterized in that: a base station sends information which carries a message that whether uplink TAs of a plurality of cells are the same to the terminal; the terminal determines whether the uplink TA of the new added cell configured by the base station for the terminal is the same with the uplink TA of a current service cell TA of the terminal; if the uplink TAs are the same, the current service cell TA is acquired and the TA is taken as the TA used in the uplink transmission performed in the new added cell; otherwise, through initiating a random access process, the TA used in the uplink transmission performed in the new added cell is obtained. Therefore, by using the method, the system and the equipment of the invention, the terminal can obtain the TA used in the uplink transmission performed on the new added cell.

The invention discloses an establishing method of a data radio bearer on an air interface. The method includes receiving an indication of integrity protection ability of the data radio bearer (DRB) sent by a relay node (RN); if the RN does not support the integrity protection of the DRB, establishing the DRB without the integrity protection with the RN or not establishing the DRB with the RN. According to the establishing method and a device, whether the RN supports the DRB integrity protection can be informed through a donor evolved node B (DeNB), therefore when the RN does not support the integrity protection ability of the DRB, the DRB without the integrity protection can be established with the RN, or the DRB cannot be established with the RN, and false data transmission on the DRB caused by inconsistent negotiation of the DeNB with the RN can be avoided.

A method and device for eliminating interference and a smart television set. The method comprises: determining whether an interference pulse exists in a current inter-integrated circuit (IIC) bus when sensing a read / write data instruction (S10); monitoring in real time a serial data (SDA) bus pulse and a clock pulse of the IIC bus when an interference pulse exists in the current IIC bus (S20); and adjusting the voltage of the clock pulse when the SDA bus pulse and the clock pulse satisfy a predetermined condition (S30). Voltage adjustment for a clock pulse when an interference pulse exists in an IIC bus is implemented, thereby avoiding the problem of data transmission error between an external apparatus and a main chip of a smart television set caused by a change in a start or stop condition of an IIC bus protocol due to a change in an SDA bus pulse and the clock pulse because of the interference pulse; and data transmission of the IIC bus is ensured by correcting the high-low level of the clock pulse.
